The freezer

1. The temperature inside a freezer is minus 23 degrees Celsius. The temperature falls by a further 12 degrees Celsius. What is the new temperature?
2. What is the difference between temperatures of 12 degrees Celsius and 210 degrees Celsius?

Correct answer:

a =  -35 °C
b =  198 °C

Step-by-step explanation:

$$\begin{gathered} t_1=-23\text{°C} \\ \Delta =12\text{°C} \\ a=t_1-\Delta =(-23)-12=-35\text{°C} \end{gathered}$$

$$\begin{gathered} t_3=12{}^{\circ } \\ {t}_4=210{}^{\circ } \\ b=t_4-t_3=210-12=198\text{°C} \end{gathered}$$
